Not long after that I had problems with the card in windows AND ubuntu (and I still have them sometimes). Sometimes the card just does not work. I have looked for a solution and let people from the IT-service in our school look but nobody of us could find a solution.

After that, I upgraded the kernel of ubuntu, which has the next problem because the driver only supported until kernel 3.3. But in the same article that I've mentioned before, someone gave a second link for kernel 3.5. But from that time, everytime I restart my computer the driver isn't working automatically. I had to enable it as an LKM with modprobe.

It worked for a while, but suddenly it stopped working. It doesn't work anymore to use modprobe to enable it and I've tried restarting, reinstalling the drivers, ... I installed almost everythink I could think of and what I could find on the internet.

Thanks for your reply! Suddenly it worked again. I had found a newer version of the driver. The only problem was that it didn't start automatically anymore each time I rebooted. So I have solved it by loading the kernel module with /etc/modules. This helped me! Now it works most of the time!
